author contributed a mineralogical description of rocks 

 from Nagpur, Central India, and described some new 

 Orthocerata from Cork and Clonmel, and Cyclostigma, a 

 new genus of fossil plants, from Kiltorcan, co. Kil- 

 kenny. Mr. Edward Brenan gave an account of the 

 discovery of mammoth and other fossil remains at 

 Shandon, co. Waterford, and Dr. Robert McDonnell 

 contributed a paper on the habits and anatomy of 

 Lepidosiren annectens. 



The principal papers in vol. iii. are those by 

 Professor E. W. Davy on ferrocyanide of potassium 

 as an analytical agent ; further contributions by Dr. 

 Haughton on the tidal currents of the Irish Sea, and 

 a paper on the fossils brought from the Arctic regions 

 by Captain McClintock. Dr. David Walker contri- 

 buted notes on the zoology of the Arctic expedition 

 under McClintock. Mr. Thomas Grubb described 

 a new table microscope, and Mr. John Dowling wrote 

 on the comparative value of the different feeding-stuffs 

 for horses. Dr. Henry Lawson suggested the forma- 

 tion of a new class of Annuloida, to include Trematoda^ 

 Planarite^ and Hirudinei^ and Mr. William Andrews 

 wrote on the cod and ling fisheries of Ireland. The 

 volume includes a catalogue of the minerals collected 

 by Sir Charles Giesecke between Cape Farewell and 

 Baffin's Bay in the Arctic regions. Mr. Charles W. 

 Hamilton's paper on the condition of the Irish agri- 

 cultural labourer in 1859 is historically interesting; 

 the tabulated abstracts of the answers to the Society's 

 agricultural queries, and the lists of labourers' families 

 which accompany the paper contain much curious 

 information. 



The following papers in vol. iv. are of permanent 

 interest : A. Leith Adams on the fossiliferous caves 

 of Malta ; Dr. Henry Lawson on the anatomy,
